fingerprint

This is a very specific question which will probably earn me the tumbleweed badge, but please answer if you can I've imported DigitalPersona sdk dll's as type libraries into Delphi and am trying to verify fingerprints which I've stored as serialized data in a database, it's working very awesomely. Enrollment seems to work fine, but I can't turn the binary data from the finger prints back into DPFPTemplate objects. I keep getting an OLEException every time I try to used the defaultinterface property of a TDPFPTemplate object. What I'm wondering is how Digital Persona expects you to use their

I have purchased a simple biometric fingerprint reader that is usually used for laptop security through a USB connection. It is just called biomentric finger print reader, not branded! It came with the software for creating security for laptop, and it works great. However, I had a different idea for it: I am intending to create a database of users fingerprints so that I can identify which user swiped their fingers on it, ie, to use it for different users' authentication using fingerprints . I don't seem to be making any head or tail on how to go about that. I would like to find out if there is

I downloaded an Enrollment Sample Code for my digitalPersona device to use. It could already register and verify fingerprints but the problem is that it save its fingerprint .fpt file in a folder. I want to save it in the database. This is what I already tried so far. private void SaveButton_Click(object sender, EventArgs e) { SaveFileDialog save = new SaveFileDialog(); save.Filter = "Fingerprint Template File (*.fpt)|*.fpt"; if (save.ShowDialog() == DialogResult.OK) using (FileStream fs = File.Open(save.FileName, FileMode.Create, FileAccess.Write)) { Template.Serialize(fs); fs.Close(); //Read

I've recently had a trouble making Galleria plugin work with Rails 4 Pipeline and it took me a while to figure out how to make it work, so I wanted to share the solution in case somebody has the similar problem. 1) After downloading the plugin, put galleria-1.3.3.js ( it's the current version on the day I write it ) and galleria.classic.js ( or other style js file ) to vendor/assets/javascripts 2) Put galleria.classic.css ( or other theme stylesheet) to vendor/assets/stylesheets 3)Add //= require galleria-1.3.3 and //= require galleria.classic to your application.js file and *= require

I want to build an android application like employee attendance using fingerprint scanner . I want to know that, Is it possible using external hardware device for fingerprint scanning? How to integrate Android application with external hardware finger print scanning device. How to fetch data from external hardware device and store data in local database. Thank you in advance. Is it possible using external hardware device for fingerprint scanning? Yes there's some fingerprint scanners compatible with Android Platform and with SDK for Android. Scanners are plugged on USB port so you can't charge

I am getting an error in my simple project. This is my code: if (axZKFPEngX1.InitEngine() == 0) { label1.Text = "Connected"; } else { label1.Text = "Connection Failed"; } I already added reference composites AxInterop.ZKFPEngXControl and Interop.ZKFPEngXControl . While debugging, I click the button, and a warning appears: InvalidActiveXStateException was handled. "Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown"** try to call CreateControl() from your component first. The answer by Constantin is Fulfill your requirement but here I wanted to add one more

Has anyone implement fingerprint recognition system in Java? For example this comes with java api for linux and windows platforms: http://www.griaulebiometrics.com/page/en-us/manual/fingerprint-sdk-java If you are interested about fingerprint recognition as such, then this book is helpful: http://bias.csr.unibo.it/maltoni/handbook/ For a fast overview, check http://www.cse.unr.edu/~bebis/CS790Q/Lect/BK2_Chapters_1_2.ppt Take a look to this open source lib which is well maintained: sourceafis-java with the official code repo: https://bitbucket.org/robertvazan/sourceafis-java/src/1ec1cb4f210d?at

I am planning to verify the user input for my application using the biometric input. I did some research on net and came up with following options of biometric input: Fingerprint Facial Recognition Retinal Scan Iris Scan Voice Recognition Signature Verification Out of which I felt the fingerprint as most suitable options. But the problem with this is the API of the fingerprint device will vary with its hardware. So most probably I think I will need to code against the multiple devices API, which I don't find friendly. I intend to do the programming stuffs in C#. Is there any way out of this.
